Show "group" and variations (Row, Stack) in multi-select toolbar

[mtias]

Let's surface the "group" action on the multi-select toolbar:

It's a more common action to do when you multi-select and it's unnecessary buried:

To-do

• BlockToolbar: Show Group button in toolbar when multiple blocks are selected #39710
• Follow up with additional buttons for Row and Stack variations

@mtias Any thoughts about whether the other MenuItem of Add to Reusable Blocks should be moved as well? Does it make sense to move the Group MenuItem from that MenuGroup and add it to the top of the list? This would mean that Add to Reusable Blocks would be the only MenuItem in that group.

@mtias After looking into this some more, it seems like the Group menu item is added to the general BlockSettingsMenuControls slot (which developers can extend and add other items as desired). Would it be useful to move this button out of this menu group and into the main group (i.e. where Copy and Paste are)?

Also, it might be ideal if the Group button remained in the same relative location regardless of if multiple blocks were selected. I can see users getting confused if the Group item were to change location in the dropdown based on whether multiple blocks were selected.

I think I misunderstood and just moved up Group Menu in my PR.

@mtias in order to add it to multi-select toolbar, we need an icon, is there any existing icon we can use?

[mtias]

@jiteshdhamaniya Yes, the group icon can be used:
